I can't get better

Lance has been training every night in secret; he believes he isn't good enough to be a paladin of Voltron. What happens when he injures himself and has to wait for someone to find him? Lance has a crush on Keith, maybe Keith can help him more than he thought, or was Keith the reason all of this started in the first place? Possible epilogue if anyone likes this. (I'm new to Wattpad please no flames; if you don't like gay couples or don't ship this, don't read. Simple)
Warnings: Mentions of self harm, bullying, depression, and self doubt, very angst-y
